This is not technically a protocol constant as partial note commitments are computed by each contract.
A partial note commitment is the first round of hashing of a partial note, combining the private fields before the
public completion fields (storage slot and public note data) are mixed in. Distinct from DOM_SEP__NOTE_HASH,
which preserves the storage-slot-first invariant.
